A touchscreen-controller and data-entry ensemble are attached conterminously or proximately to a touchscreen device. A touchscreen-controller attachment device has one or more input ends and one or more output ends. The input and output ends may be opposite ends of unitary elements and/or may be remote from one another and connected by wire or wirelessly. Each input end of a unitary conductive element is connected to a respective output end and the plurality of output ends, residing in an attachment base, are in a position of contact with or in close proximity to the soft buttons, keys or controller(s) of a touchscreen. The output ends thus activate the touchscreen when the input ends are manipulated. A base maintains the input and/or output ends in fixed position during use. Input and output elements can be spring-mounted. New controllers offer the user haptic ability.
